What is a conditionally essential vitamin?
Conditionally essential nutrients (CENs) are organic compounds that are ordinarily produced by the body in amounts sufficient to meet its physiological requirements. However, in disorders, such as cardiovascular disease (CVD), and in other physiologically stressful conditions, their biosynthesis may be inadequate.

The triage theory (Ames, BN (2006) PNAS 103-‐17589-‐94) posits that the spectrum of functions for a particular vitamin or mineral (V/M) are managed by the organism such that, when micronutrient availability is limited, functions required for short-‐term survival take precedence over functions whose loss can be better …
How do you test for vitamin C deficiency?
A blood test can be taken to measure vitamin C levels and may help to confirm the diagnosis. Your doctor may also suggest some other blood tests to check for other deficiencies in your diet. For example, vitamin C is also needed for the absorption of iron from food.

What does it mean to triage vitamins?
The triage theory posits that some functions of micronutrients (the approximately 40 essential vitamins, minerals, fatty acids, and amino acids) are restricted during shortage and that functions required for short-term survival take precedence over those that are less essential.
Who gave the vitamin theory?
The term vitamin is derived from the word vitamine, which was coined in 1912 by Polish biochemist Casimir Funk, who isolated a complex of micronutrients essential to life, all of which he presumed to be amines.
Which is an example of a conditionally essential nutrient?
The feed- ing studies that have been done have, in the nutrients studied, demonstrated what occurs in healthy, young individuals who are depleted of a single nutrient. Carnitine, taurine, arginine, cysteine, glycine, choline, are all generally recognized conditionally essential nutrients.
Which is an example of a conditionally essential amino acid?
As a result of these demands, the body’s supply of nonessential amino acids must be provided by the diet. Arginine, glutamine, and cystine are examples of conditionally essential amino acids that have been combined with other nutrients in supplements formulated for wound healing. Arginine.
Why are vitamins classified as essential or nonessential?
Nearly all nutrients that are classified as vitamins are obtained through dietary means, which is indicative of the term essential, because the body cannot synthesize these compounds. There are only a few vitamins that are considered nonessential because the body is capable of synthesizing these nutrients.
Why is it important to check your vitamin and mineral levels?
Vitamins and minerals are types of micronutrients — something your body needs in tiny amounts. They influence nearly every process in your body and are essential for your health. You can check your vitamin and mineral levels with a personalised blood test.
